Video coding standards are essential to a wide range of applications, but have certain limitations. New, flexible approaches to video compression have the potential to speed up adoption of new coding techniques, to improve compression performance through adaptive coding and to support multiple coding standards on a single platform. In this paper we describe the MPEG Reconfigurable Video Coding ...

the transformation of 2D-DCT is applied in video compression technique with 14 additions for area and power compaction. The proposed structure could be implemented in 4, 8, 16, 32 bit size. The proposed 2D-DCT system is used to reduce the complexity of video compression. It results in less area delay and power consumption with “0” and “1” by implementing in FPGA. HEVC/H265 is applied for enhanc...

\It is my thesis that worthwhile improvements can be made to lossless image compression schemes, by considering the correlations between the spectral, temporal and interview aspects of image data, in extension to the spatial correlations that are traditionally exploited." Images are an important part of today's digital world. However, due to the large quantity of data needed to represent modern...

One of the top tasks for video streaming, video surveillance, video conferencing and video broadcasting is a low-complexity and real-time video coding and transmission over wireless channels. Taking into account high bit error ratios, packet losses and time-varying bandwidth of wireless systems, the scalable video coding (SVC) is more preferable as compression method for wireless video transmis...

This chapter we first presents various video representations and formats. Then, an overview of video compression techniques is given. Two standards and related techniques are described and evaluated – px64 Kbps (or H.261/H.263) standard for video-based communications and MPEG standard for intensive applications of full-motion video. Both standards use the combination of DCT-based intraframe com...

Video is the key element for the growing trends in the mobile industry. Reducing the amount of video data that can be transmitted over a connection is strongly recommended to meet out the bandwidth requirements. Video compression is a coding technique which reduces the actual number of bits than the original data and hence the bandwidth is increased. In this work, a detailed study is done on vi...

Video compression has been the object of intensive research in the last thirty years. Video compression technique is now mature as is proven by the large number of applications that make use of this technology. This paper gives the idea about different techniques available for video compression. H.264/AVC exhibits superior coding performance improvement over its predecessors. The next generatio...

Digital video compression technology continues to evolve, and the choice of systems presents a difficult challenge for broadcasters and web content providers. In this article, the author explains some of the factors shaping the evolution of video compression technology, and offers some insights into the comparative performance of video compression systems. The article is based on a presentation...

Almost everyone in the industrialized world uses video compression many times each day. Whether you’re watching Oprah on TV, funny clips on YouTube, Disney on DVD or homemade movies of your family, all video storage and delivery mechanisms rely heavily on compression technology. As early as 1929, Ray Davis Kell described a form of video compression and was granted a patent for it. He wrote, “It...

Traditional video compression algorithms focus on causal processing of the video data. The causal constraint is necessary for real-time video programs where delay is an important consideration. However, many video programs such as movies are pre-recorded and can be processed offline prior to compression. This thesis proposes using pre-processing for pre-recorded video programs to obtain useful ...
